XXX.—On the Geographical Distribution of the Genus 
Cosmophila, a Noctuid of the Family Gonopteride. By

(Plates IX. & X.] 
Family Gonopterida. 
Genus CoSMOPHILA, Boisd. 
Faun, Ent. Madagascar, p. 94 (1883). 
Type, eanthindyma, Boisd. l. ¢. 
a very interesting genus, well worth careful investigation. 
Heretofore, on account of the similarity of pattern, authors 
have put all the different forms from America to Australia, 
regardless of the localities, mostly under the American form 
erosa; in ‘ Moths of India,’ ii. p. 411 (1894), Hampson puts 
xvanthindyma, Boisd., from Madagascar, indica, Guen., from 
India, auragoides, Guen., from Natal, variolosa, Walker, 
from North India, and edentata from Queensland all as 
synonyms of erosa, Hiibner, from America, 
Staudinger, in his Catalogue, 1901 edition, puts xanthin- 
dyma, indica, and auragoides under the American form. 
Warren, in Seitz’s § Macrolepidoptera of the Palaarctie 
Region,’ vol. ii. p. 359 (Nov. 1913), puts auragoides, vario- 
losa, and edentata as synonyms with wanthindyma; umder 
erosa he puts indica. 
The superficial pattern of all these is more or less the same, 
but there are differences. I could not get myself to believe 
that, notwithstanding the geographical distances, they could 
all be one and the same species, and consequently I got the 
Rev. ©. R. N. Burrows, who is an expert on the genitalia of 
Lepidoptera, to examine specimens from many different parts 
of the globe, and I am very grateful to him and to Mr. FN. 
Pierce of Liverpool for the pains they have taken in the 
matter. All the Plates are from drawings by Mr. Burrows, 
and all the notes on the genitalia are his, many of them 
having been submitted to Mr, Pierce for verification. 
Mr. Burrows says that the dissections show a relationship 
to the Hrebusidew, to the genera Argiva and Patula in the 
large extensile coremata, dorsal of the valves; he further
